COMMINUTING MACHINE.

Appucation filed April 12, 1928. serial N. 269,399,

j This invention relates to comminuting machines for rapidly reducingalfalfa and the like to form a stock feed and of that type including acomminuting head and a'grading cyiinder or screen for the passage of thefiner particles of the feed, and the invention has for its object toprovide, in a manner as hereinafter set forth, a machine of the classreferred to having means to permit of the passage of ccarser particlesof the feed to a point of discharge when it is not desired to have afine ration, as would be had if the fine parpoint of discharge.

A further obj ect of the invention'isto provide, in a manner ashereinafter set forth, a machine of the class referred to including adjustable means for `permitting of the pasticles of the feed alone havepassed to the sage of coarser particles of feed to la pointv ofdischarge when desired.

A further object of the invention is to provide, in a manner ashereinafter set forth, a machine of the class referred to includingmeans in the form of van adjustable by-pass for increasing the capacityof the machine.

A. further object` of the invention is to provide, in a manner ashereinafter set forth, a machine ofthe class referredfto with anadjustable by-pass for the feed` for use when the farmer does not careto 4have as yfine a ration as would be obtained providing it was run allthrough the cylinder or screen and further whereby the capacityof themachine is increased when the` by-pass is open.

Further objects of the inventionl are to provide, in a manner ashereinafter set forth, an adjustable by-pass for'use in comminutingmachines of the class referred to/and which is simple in itsconstruction and arrangement, strong, durable, thoroughly efficient inits use, readily installed in the machine, conveniently opened andclosed, as well as adjustable, and comparatively inexpensive to set up.i

With the foregoing and other objects in view the invention consists ofthe novel construction, combination and arrangement of arts ashereinafter more specifically described, and illustrated vin theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which fall within' the i `scope of the claimshereunto appended. j

An adjustable by'pa`ss, Ain accordance with this invention, is shown asinstalled in acomminutingmachine of that type illustrated by LettersPatent. 1,190,499, July 11, 1916, in which a rotatable grading ,cylinderfor the passage of the finer particles of the vfeed forms a partJthereof, but it is to be understood that an adjustable bypass,inlaccordance with this invention, may be installed in any type ofcomminuting machine for 4which :the by-pass is found applicable andwhether the lgrader is in the formuof a rotatable cylinder `orstationary` screen. l, f

y It is thoughtunnecessary to specifically describe the elements ofthemachine, as such specific details can be ascertained by reference `ltoLetters Patent aforesaid, `and such elements will be referred togenerally and in this con- 4 nection 1 indicates a rotatablecornmijnuting element, 2 thefrotatable grading cylinder or `sifterarranged below, the element 1, 3, 4

centenand llower feed Arolls respectively arranged adjacent to theelement 1 and cylinder 2; 5 upper feedroll, 6 feedinglmeans for stock, 7cover for the element 1'; 8 covers for lrolls 3, 5; 9 feed throat, 10cover for throat 9,

11 upper ledger plate, 12 upper ledger plate holder, 13 lower ledgerplate, 14 lower ledger plate holder, 15 lower section of hood 7, 16mainframe or housing, 17 feed throat side, 18 perforated, pivotedsegmental sections of the cylinder 2 g 19 guide for controlling thesections 18 of cylinder' 2; 20 ,main frame, 21

- Support for frame`20; 22 front tie barplate, v23 rear tie bar plateand 24 discharge conveyor or wormarranged in the top of frame 2O andbelow the lower ends of plates 22, 23.

. The plates.22,.23 "are disposed at opposite in-v clinations withrespect to each other and between the lupper portions ofthe plates 22,23,

as well as spaced therefrom is the guide 19.

' 22 whereby a passage 25 is provided nor-v mally closed by a pivotedplate 26 carried byA It will be stated that two guides are employed, oneat each end ofthe cylinder 2. rIhe foregoing elements are illustrated sothat the adaptation of an adjustable by-pass in ac` cordance with thisinvention and for the purthe comminuting element 1 and said' cylin-V der2 is further spaced from the front plate the lower ledger plate holder14. The plate 26'is pivoted at its outer side, to the plate 14, as at27. The plate 26 is provided on its outer side with a-pertured ears 28,only one of which is shown and through'which eX- tends the pivot 27, thelatter also extending through or connected with the bottom of the plate14.y yThe plate 26 is of a length substantially the same as the lengthof the ele.n ment 1 and cylinder 2 and said plate 26 constitutes agatefor closing the passage 25 and will be hereinafter termed a gate. Thegate at each endl andy at its inner side is formed with a dependingflange as indicated at 29.

The width of the gate 26 is Asuch that when it is in a position to closethe'passage 25 it will extend into close proximity to and between theguides 19. l

The opening movement of the gate 26 is adjusted, andl the means'foradjusting the gate 26 also provides for not onlyretaining it in adjustedposition, but also lretaining the gate26 in closed position for shuttingolic communication between the upper portion of the passagey 25 and thelower portionthereof. The means coacting with the gate 26 .for thepurpose ofretaining it in closedl position as well as inadjustedposition, consists of a screw 30 having its inner end riding against thelowerA face'lof the lgate 26. The outer end of the screw 30 is providedwith an enlarged head 31 to provide for'theconvenient shifting of thescrew. The plate 22 is formed with an opening 32 having a threaded wallwith which engages the screw 30. The plate 22 is also provided with aboss on its outer face and adapted to be engaged by the reduced innerpart 33 of the head 81. 1

When the gate 26 is in closed positionV the vcommin'uted material willbe caused to pass solely through the cylinder 2'but the comminutedmaterial must be of such size as to pass through the openings in thesections 18. If `it be desired to permit of the discharge of the coarserfeed which? cannot pass through the sections 18, the gate 26 isadjuste'dto the desired extent to open the passage 25 whereby the saidcoarse material can pass between the gate and the cylinder 2 to thepoint of discharge which is the conveyor or worm 24.

The gate 26, when 'adjusted in position to l lsaid by-pass.

close the passage 25, as illustrated in Figure i v 1, is slightlyinclined in a. downward direction from its pivoted end -to its free end,and as the screw 30 is withdrawn from the passage 25 by the rotation ofthe screw, the gate 26 is actuated by gravity inthe same direction asthe direction of travel of the feed particles through the passage. Byonly partially withdrawing the screw 30 from the passage 25, the gate 26may be adjusted at the desired inclination to close any predeter minedportion of the passage. l

In some instances the farmer does not desire a ration formed of theiinest particles ofthe feed, that is to say those particles which ypassthrough the sections 18 of the cylinder and if such loe the case thegate 26 is opened to the desired extent so that the coarser particles,not vpassing 'through 'the cylinder 2, will be permitted to pass betweenthe gate 26 and the cylinder 2 to the conveyor er worm 24 ywhere thecoarser particles would mix with those finer particles which have passedthrough the cylinderk 2, or if none of the liner' particles are at theconveyor or worm 24, then there will be no admixtur'e of the' coarserparticles with the hner particles. The opening of the gate26 increasesthe capacity of the machine.

The gate 26, inconnectionwith the adjusting screw 8O and passage 25providesa by-pass whereby the machine can be controlled so that thecoarser particles of the feed will be permitted to pass to a point ofdischarge. The'gate 26 can be so adjusted that liner particles landcoarser particles can be simultaneously'supplied to the conveyor or worm24, the finest particles passing through the cylinder 2 andthe otherparticles between the gate 26 and thecylinder 2.

Itis thought the many advantages of a. comminuting machine of the classreferred` to provided with a by-pass,in` accordance with this invention,can be readily under. stood, and although the preferred embodiment ofthe invention is as illustrated and de scribed, yet it is to beunderstood that changes in the details of construction can `be had which4will fall withinthe scope vof the invention as claimed.
